Hello again,
Patrick states that he was born County Meath in both 1901 and 1911 censuses and Margaret states Meath in 1901 and Cavan in 1911.
Looking at the children in 1901 there is a Lizzie Keenan 12 yrs and Alice McPartland stepdaughter 12 yrs. Sometimes are inaccurate by a couple of years but this would indicate that Patrick and Margaret were married after 1889.
There is a Bethana Partland born 1884 Oldcastle district which would fit with 1901 census. Similarly, there is an Alice -1887

Oldcastle.
However, I can't see a marriage for a Patrick Keenan to Margaret McPartland

I was hoping that if there was a marriage, you would get Patrick's father's name.
regards
heywood
